Wayne State study seeks to cut mercury pollution

DETROIT (AP) — Scientists at Wayne State University are using a $557,000 grant to develop a system for reducing the amount of poisonous mercury that power plants pump into the air when they burn fossil fuels.

The Detroit school says the Great Lakes Protection Fund is paying for the 2-year project, directed by engineering professor Carol Miller.

Wayne State says Miller’s team will “refine, test and market” a technology that interacts with power grids “to precisely estimate the emissions associated with current power uses.”

The system is designed to let power companies know immediately when cleaner forms of energy are available.

The technology is called Locational Emissions Estimation Methodology and was pioneered in a project previously supported by the fund.

U-Michigan engineers study malware in hospitals

ANN ARBOR (AP) — Two University of Michigan engineers are part of a national team that is using a $10 million federal grant to protect medical devices and hospital computer systems from viruses and other malware.

The university says associate professors Kevin Fu and Michael Baileys are participating in a 5-year Trustworthy Health and Wellness project, financed by the National Science Foundation.

Fu and Bailey say they will establish methods to scientifically study the extent of malware in hospital networks. They say it’s important to get detailed data and not to simply rely on anecdotal reports.

DETROIT (AP) — Authorities say eight people traveling from Detroit to mark the 50th anniversary of the 1963 march on Washington were injured in a bus crash, while more than 40 others escaped injury when their homebound bus was destroyed by fire.

Police say the injured were taken to a hospital for treat injuries that weren’t life-threatening.

Early Sunday, the Ohio Highway Patrol says a Detroit-bound chartered bus with more than 40 people aboard caught fire from a blown tire. No injuries are reported.

Tens of thousands of people marched to the Martin Luther King Jr. Memorial and down the National Mall on Saturday.

W. Mich. covered bridge reopens after truck damage

VERGENNES TOWNSHIP (AP) — West Michigan’s last remaining original construction covered bridge has reopened after a truck that weighed more than 10 times its load capacity damaged the span.

The 31-ton cement truck damaged the interior cross-bracing of the 142-year-old Fallasburg Covered Bridge on Wednesday, according to The Grand Rapids Press (http://bit.ly/178I2gS ). It reopened a day later after Kent County Road Commission engineers inspected it.

“It did not compromise the structural integrity of the bridge,” Steve Warren, road commission director, told the newspaper. “We felt confident in reopening the bridge to vehicular traffic.”

He said he did not know why the 37-year-old driver crossed the bridge, which is marked with 3-ton limit signs.

Steel rods placed on the bridge in the 1930s and replaced in 1994 likely saved the bridge, said bridge inspector Tom Byle.

“If those tension rods hadn’t been added, it would have been in the river,” he said.

The incident comes just weeks after an arson fire destroyed the Whites Covered Bridge, which is just a few miles up the Flat River from Fallasburg.

Prison system credits Tasers for guard attack drop

LANSING (AP) — Michigan’s prison system is crediting the introduction of Tasers for a drop in attacks on its employees.

The Michigan Department of Corrections issued the electronic stunning devices in five prisons in December 2011 and expanded the deployment system-wide last year.

The Lansing State Journal says a Michigan prison employee uses a Taser on a prisoner about twice a day. It says there have been 576 Taserings since Oct. 1, 2012.

The Corrections Department says prisoners attacked employees 579 times in 2012, down from 644 in 2011 and 688 in 2010.
